  • Patent number: 8966645
    Abstract: Text entry context information associated with text entry within an inter-user communication application is evaluated. A determination is made as to whether the evaluated text entry context information identifies a text string entered by a user as a potential password inadvertently entered into the inter-user communication application by the user. In response to determining that the text string is identified as the potential password, the user is prompted to confirm that the user intends to send the text string using the inter-user communication application. The text string is transmitted using the inter-user communication application in response to a confirmation from the user to send the text string.

  • Publication number: 20150052326
    Abstract: A request is received to load a first page into main memory with the main memory containing a plurality of page frames. It is determined that none of the plurality of page frames is an empty page frame. User input is referenced to determine a target memory resource consumer. A second page is selected which is loaded in a first page frame. The second page is associated with the target memory resource consumer. The second page is moved from the main memory to a secondary storage device. The first page is loaded into the first page frame.

  • Patent number: 8904384
    Abstract: A computer-implemented method is provided for reducing network traffic associated with live migration. The method comprises selecting a virtual machine on a first physical host for migration to a second physical host, and providing each application running in the selected virtual machine with notification that the migration has started. In response to receiving the notification that the migration has started, each application reducing the number of memory pages in use during the migration. The selected virtual machine and each application is then migrated from the first physical host to the second physical host, wherein the migration of each application includes migration of the reduced number of memory pages.

  • Publication number: 20140298489
    Abstract: A method, data storage device and computer program product for having multiple users share a single data storage device securely. A data storage device, such as a Universal Serial Bus (USB) key, is plugged into a computing device. A USB controller of the USB key recognizes the computing device and creates an account for the user. The created account is associated with the user as well as associated with the computing device. Data uploaded to the USB key by the user is then associated with the created account. Only that user will be able to view that data on his/her computing device (computing device associated with the created account) unless the user indicates to share that data with other users. Such a process may be repeated each time the USB key is plugged into a different computing device thereby creating multiple accounts associated with multiple computing devices and users.

  • Patent number: 8776033
    Abstract: A batching mechanism is provided that batches multiple Java Native Interface calls together such that the batch crosses the Java Native Interface boundary in a single transition. The batching mechanism operates by identifying a sequence of Java Native Interface calls to be made by native code, by encapsulating the identified sequence of Java Native Interface calls into a batch, and by communicating the batch as a single transition across the Java Native Interface boundary. In this manner, each call of the batch is encapsulated by iteratively performing for each call to be made, processes including identifying the Java Native Interface function to call, identifying the arguments to pass into the Java Native Interface function, dispatching to the Java Native Interface function and capturing the return value.

  • Publication number: 20130275965
    Abstract: A method for providing control of Java resource runtime usage may include establishing communication with one or more Java virtual machines (JVMs) forming a hive via a hive communication channel where the hive comprises a plurality of JVMs configured to enable utilization of at least one shared resource, receiving, via the hive communication channel, environmental information indicative of hive activity relative to the at least one shared resource from at least one of the one or more JVMs, and adapting, via processing circuitry, operations associated with use of the at least one shared resource based on the environmental information.

  • Patent number: 8499010
    Abstract: Garbage collection processes are automatically tuned on a system comprising a plurality of virtual machines running on a physical processing device with multiple physical processors. Tuning is implemented for each garbage collection process, by updating a load variable to reflect that a new garbage collection process has started, the load variable having a value that is based at least in part on a number of garbage collection processes that are currently running on the system. Tuning further comprises creating a number of garbage collection threads based at least in part on the current value of the load variable and/or number of processors, where the garbage collection threads are used to perform at least a portion of at least one phase of the new garbage collection process. Tuning further comprises re-updating the load variable to reflect completion of the new garbage collection process.

  • Patent number: 8341643
    Abstract: Shared memory and sockets are used to protect shared resources where multiple operating systems execute concurrently on the same hardware. Rather than using spinlocks for serializing access, when a thread is unable to acquire a shared resource because that resource is already held by another thread, the thread creates a socket with which it will wait to be notified that the shared resource has been released. The sockets may be network sockets or in-memory sockets that are accessible across the multiple operating systems; if sockets are not available, communication technology that provides analogous services between operating systems may be used instead. Optionally, fault tolerance is provided to address socket failures, in which case one or more threads may fall back (at least temporarily) to using spinlocks. A locking service may execute on each operating system to provide a programming interface through which threads can invoke lock operations.
